RAIL-JOINT.

Specification of Letters Patent.

Patented Nov. 2, 1915.

Application filed August 17, 1914. Serial No. 857,147.

To all whom it may concern: 7

Be it known that I, OHARLEY M. Cox, a citizen of the United States, residing at Burr, in the county of Rockcastle, State of Kentucky, have invented certaln new and useful Improvements in Rail-Joints; and I do hereby declare the following to be a full, clear, and exact description of the nvention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to a rail joint.

An object of the invention is to prov de a joint for securing together thetwo ad acent ends of rail sections.

A further object of the invention is to provide a device of this character which w1ll secure the ends of the rails together and yet will allow the same to expand or contract as affected by the heat or cold respectively.

A still further object of the invention 1s to provide such a device that the rails will.

be prevented from all relative vertical movement.

With these and other objects in view, such as will appear as the description progresses,

my invention comprises the combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which: I

Referring to the drawing: Figure 1 s a perspective view of my device. F 1g. 2 s a side elevation thereof. Fig. 3 is an end view of the device. Fig. t is a vertical longitudinal section. Fig. 5 is a longitudinal section taken on a horizontal plane. Fig. 6 is a plan view of the device.

Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views :My device comprises two rail sections 1 and 2 having enlargements on their adjacent ends, the enlargement on the section 2 comprising on the inner side of the rail a vertical wall 3 which is made integral with the web, the base and the tread of the rail and extends upwardly from the said base to a point slightly below the plane of the lower face of the tread and it is then out oif and inclined upwardly to the edge of said tread. On the other side of the rail is integrally formed a wall 4 which is of a formation similar to that of the wall 3 with the exception that it extends up to the plane of the upper face of the tread and forms a part of said upper face. The enlargement 5 on the other rail section 1 is in cross section similar to that on the rail 2, but the length of the said enlargement is considerably greater than the length of the enlargement on the end of the section 2 for the purpose as hereinafter to be described. Formed in the enlargement 5 is a socket 6 which is of dove-tailedformation in horizontal section and extends upwardly in the said enlargement from the lower face thereof. The upper face of this socket is parallel with the lower face of the base member of the rail and lies in a horizontal plane. On the end face of the rail section 2 and integral with the enlargement on the end thereof is an outwardly projecting dove-tailed tongue 7 which is the socket in the enlargement 011 the rail 1, but is of such dimensions as to allow the said tongueto have a slight amount of 1ongltudina movement within the said socket so that when the rails are held together by the engagement of this tongue and the socket the rails may be allowed to expand or contract by virtue of the loose connection between the tongue and the socket. Projecting outwardly from the base portion of the section 2 is a flange 8 which is integral with the tongue 7 and 'fits within the cut-away portion 9 in the lower face of the enlargement 5 on the end of the section 1. These rails after having been joined in the manner described are placed on. a base plate 10 which has a flat supporting portion 11 on which the bases of the rails rest and on one side of the said plate and extending throughout its length is an upwardly extending flange 12. This flange portion engages one edge of the base of the rail. On the other side of the base plate 10 is formed at each end thereof an upwardly and inclined projecting hook-shaped members 12 which members overhang the bases of the rails and lie in contact with both the base of such shape as to fit within i and the web clamping the rail in place upon 7 the supporting plate 11.

A slot 13 is formed in the base 10 adjacent the flange l2 and extends parallel thereto. Slidably mounted in this slot 13 and dovetailed therein is a plate 13 having a hook 13" on one end thereof which overhangs and engages the base of the rail. This plate 13 is provided with a plurality of holes 14" to accommodate spikes to maintain the device in place on a tie. These hook-shaped members 12 are spaced apart tions are separated in expanding there will be allowed between the hook-shaped members sufiiclent space to allow such expansion.

It is to be understood that these enlarge ments on the outer side ofthe railproj'ect between the hook-shaped members and c0- act with the hook-shaped members to prevent longitudinal movement of the rail.

Between the hook-shaped members on the edge of the supporting plate 11 is an upwardly extending flange 14 which contacts with'the lower edge of the enlargements and has notches l4 therein-in which are adapt.- ed to be engaged spikes for holding thisside of the base plate to thetie. It'istobe noted that I lHtVG'PI'OViClGCl a device which will successfully hold the'ends of two rail sections together, yet which will allow the said sections to expand under the action of heat.

I have further provided means whichwill prevent the movement of the rail sections bodily in either a longitudinal ora vertical direction, and I t have still further provided means which will preventthe movement-of the said rail sections in a transverse direction. I i do not wish to be limited to the-particu lar embodiment of my invention shown, for it is obviousthat numerous changes may be made within thescope ofthe claims without departing from the spirit of the invention.

WVhat is claimed is 1. In adeviceofthe class described, two rail sections, enlargements on theend of each section, a dove tailed socket formed in one enlargement, a dove-tailed tongn'e on the other enlargement and extending into the said socket, a plate projecting from one of said enlargements and integral with said tongue adapted to'fit in a cut-away portion in the other enlargement, a base plate comprising a supporting plate, an upwardly extending flange on one edge of saidsupporting plate, hook-shaped members on' the other edge of saidvsupporting plate and at the ends thereof, said members projecting over the base of therailsa'ndclamping the same between them and the supporting plate, the distance'between the inner faces of saidhooloshaped membersbeinq slightly greater than the combined 'lengtl enlargements 0n the rail sections, and a flange formed on the edge of said support,- ing plate between said hookshaped Them aers. r

2. In a device of the class described, rail having a socket on one end thereoia second rail having a tongue on the end thereof constructed and arranged-to interlock in -said*soeket, a *platefor supporting a the base of the rail-eonsistingofabase up wardly extending hook-'slraped -members constructed and ai-ran'ged to ejn'gage -the ends, of therail'sonone side of the web thereof, the "said base plate having a groove formed in 5 the} o posite: side tlier'eoffa plate sli dabl v mounted in said groove a hook-shaped member formed integral with said p'late and constructed 1 to engage one of -the rails upon the opposite side of the web.
